elevation of the supporting Be it known that 1, CHARLES M.-WEBB, acitizen of the United States, residing at Los Angeles, in the county .ofLos Angeles and State of California, have invented new and usefulImprovements in Vehicle-Seats, of which the following is aspecification.

This iiavention relates to a vehicle seat havingback and seat portionsacting as a unit and supported to move in a floating manner with respectto the vehicle body.

Heretofore, it has been the genera-loustom to fasten the back and seatcushions of automobiles to the seat frame, so that the road shockscauseup and down vibrations of the passenger on the seat cushion. he backcushion being fastenedto the car moves up and down withthe latter, butnot with the passenger whose back frictionally en gages the back cushioncausing discomfort. It has been proposed to provide a seat having a seatcushion and a back cushion which move togetherin unison, and thisinvention pertains to-such a seat construction.

The primary object of this invention is to provide a seat Whose seatcushion and back cushion are not only supported'to move; upwardly anddownwardl in unison, but are also supported to move forwardly andbackwardly to accommodate the passenger to shock in the line of travelof the car.

Another object of this invention is to provide a seat, which maytiplaterally' so as to accommodate it to uneven loading by reason ofpassengers of different weights occupying opposite sides,or a lessnumber of passengers than the seatwas designe for occupying one end.This results in any number of passengers riding comfortably regardlcssof their weight and position upon the seat.

' Other objects of this. invention are, to provide a construction, whichis simple. and may be embodied within the design of vehicle bodieswithout material alteration or radical change thereof; and to provide amounted. so that 'it can be easily and expeditiously removed andreplaced in the body. l

I accomplish the embodiments 0 these objects by means of f my inventionilhfstrated in the accompanying drawing, in hioh:

. bers are hinged to each other.

Referring more particularly to Figs. 1 to 5 inclusive, the supportingframe for the seat is indicated by 10,- and comprises a seat box 11.which; is

I built up from the floor of a vehicle body and is rectangular in shape.Mounted upon the top frame members of box 11- are channel irons 12,which serve as guide tracks. The tracks are disposed at the oppositeends and across the middle of the seat but in parallel relation to eachother. A spring frame 13 is mounted above thebox and is supported insliding relation the guide tracks by means of guide 1 1. The guide barsare built up as shown'in Fig. 5 of wooden strips 15 secured to thespring frame 13 and fiber strips 16 secured to the under side of thewooden strips. The fiber strips 16' fit slidingly within the channels inthe guide track. This constructionprovides for the sliding movement ofthe seat backward and forward with relation to the body of the vehicle,rendering lubrication unnecessary and eliminating all noise andsqueaking.

upon bars (oil springs 17 are mounted upon the spring frame and supporta rectangular seat frame 18. This frame is separate from the springs 17and their frame and merely rests thereupon.

The border pieces 19 of'ihe seat frame are beveled upon the inner facesas $ldlQflt6liIl Fig. 1. Tacked to the border p eces 19 is a webbing 20.lilbunted on top of the web hing 20 and securedto the pieces 19 arestrips 21;. Secured upon the x is a webbing 2'3. Disposedbetweenwebbinge 20 and '22 is it layer of tipbolstering 23 formed ofhair on any other suitable matop .of strips 21' loo tcrial. 'Disposedupon the upper webbing 22 are sent springs 24, which in turn supand.guide. bars 14.

22 causes the latter to downwardly andwith it webbing 20 andupholstering The beveled. faces of the border pieces 19 prevent thewebbing from being cut. As the webbing sags downwardly, 'it reaches andrests upon the springs 17. By this arrangement the cushioning action ofboth sets of springs and the upholstering between the webbings andcovering combine in supporting the weight'of the occupant of the seat.

Secured along therear edge of the seat frame 18 is a back-frame 28. Thisframe,

as shown in Fig. 1, is rigidly fastened to' the seat frame in (anysuitable manner. The

back cushion29 is built up on the frame ini any well known manner.Secured to each of the end 316098 of the back frame are nockers. Reerring to Figs. 2 and 4-. rocker 30 is of channel form and secured tothe frame by means of a pivot pin 31. Secured to the outer'faceof therocker is a guide bar 32. The guide bar is built up of a wooden strip 33secured to the rocker, and v has mounted thereon a fiber strip 34.Pivo-t'a'lly secured to the. side of the supporting frame are guidechannels 35, best shown mounted in the channel of the guide 35. in Fig.3. The fiber strips 34: are slidably- This provides for movement of theseat and back frame forwardly and. backwardly, and

permits the back frame to move upwardly, and downwardly. the seat" totip laterally without disalincausing jamming of the bars in the guides.

In order to, maintain the back in normal" position, arms 36 are pivotedto the back of the supporting frame and pressed' forwardly against theseat back by means of coil springs 37. Fiber wear plates may be mounted'on the back for arms 36 to ride thereon. The forward movement of theseat is accommodated by. the track channels 12 This movement is limited,howevenby asprin 38 is in hontact with the pivoted arm 35. i pring 38counteracts and resists the action of arm 36. The seat isthus'held'resiliently against forward and backward The rockers 30-permit I spring 38 'mounted within a casing39, and so disposed that theframe 13, horizontal tracks'and sliding bars, and springs 17 are thesame as i heretofore described. The seat frame 41 is rectangular inform, and has built up thereon the seat cushion in thesamc manner as theconstruction shown in Fig. 1. The back frame 42 with its back cushion isalso the same as shown in Fig. 1, and the back frame is guided by thestructure heretofore described. However, the seat frame 41 and backframe 42 are yield-ably connected by :i spring brackets 43. The upperarms of the brackets are bolted to the back frame and the lower arms areformed with key slots 44: extending longitudinally along the arms. Theseslots are adapted to receive lock pins 45, which are secured to thebottom of the seatframe 41, and extend downwardly so that their enlargedheads may pass through the key ,slots. and engage the shoulders formedby the reduced slot portions. The lower arm of the middle spring bracketextends thewidth of the seat frame andis offset at the forward end asindicated by .46. At the offset portion is a catch pin 47. This $101548formed in a locking cam 49. The com 49- is pivoted to the under side ofthe key frame sothatit may be swung to draw the seat and back frametogether. When the seat frame is in the-position shown in Figs. 7'and8,.the seat and back will be locked together and will operate as thoughthey, were firmly bolted to the spring bracket. If it is desired topermanently fasten the seat and back, both arms of; the spring bracketsmay be rigidly 'secured to the. rame memers. e The sectional view inFig. 9 illustrates another form of connectionbetween the seat frame andback 'franie., qIn this construc- 4 tion, the back frame 50 is securedto the Seat ing the guide bars 32' and channels 35, or;

22 downwardly. As the webbing is fastened to the frame 18, the weight istransferred by the frame to some ofthe springs 17. As the webbing'sagsdownwardly it reaches and is supported upon'other of the-springs.17.

pin is adapted to registerwith an eccentric v 24 and then to stretch theWebbing 20 and .L

The seat cushion accommodates itself to the body of the'passenger, whilethe springs 17 take up the greater part of the road shock. lnecase thevehicle encounter-ea bump or steps suddenly the'seat will slideforwardly upon the-seat box 11. Asthis action takes place the channelguides 35 will swiilg along the channels. "Forwardmovement of the seatis resisted and limited by the springs 38. By this means they entireseatwill'move forwardlymnd will not cause the occupant I to slide overthe cushions as" it is common and seat framehave.

with rigidly held seats. Sudden starting causes the to slide baokwardlagainst the. action; spring 'arms 36. Vertical imovementof the seat willbe effected as a unit, the seat being resiliently supported .upon thesprings 17.

The operation-of the form of seat shown in Figs. 6 to 8 is identicalwith the device Just described. In additioiu the back frame a slight.folding movementdue to their connection by the spring brackets. Asimilar operation is obtained with the -use of the connection shown inFig. 9. i If the seat is unevenly loaded. one side will be depressedmore than the other. This causes theseat to tip laterally. The rockersswing on their pivots to: acconnnodate themselves to the inclination ofthe seat and at the same time maintain the alinement of i the guide barsand guides. By this means jamming-of the guide bars in theguide channelsis prevented, and free and easy movement of the seat is maintained.

Itwill thus be seen that a seatv embodying my invention will support oneor more persons regardless of their position on the suit ordiiferencesin weight; that all road shocks are absorbed; that the backof the passenger does not slide up and down over the back' of the seat.nor does he slide forward and backward over the seat cushion. T heseatis supported so that it has substantially a universal movement-withrespect to the. vehiele and is resiliently supported in its ,movement inany direction with respect to the vehicle.
